Histories of Australian Odonata. No. 4. Further Notes on the Life-History 
of Petalura gigantea, Leach. By R. J. Tillyard, M.A., F.E.S. — This 
paper practically completes the account of the life-history of Petalura gigantea. 
The living nymph, hitherto undiscovered, was found in a swamp at Medlow, 
Blue Mountains. These larvae burrow in the peaty substance of the swamp, 
and construct channels both vertically and horizontally. They are soft, flabby, 
whitish creatures, almost certainly nocturnal feeders and possibly blind. They 
appear to be at least two years in reaching maturity. The gizzard of this 
larva is of a very simple construction, containing eight folds with usually 
one or two small teeth on each, sometimes more. It is the only known 
Anisopterid gizzard with eight folds. The structure of the anal end of the 
larva, showing a distinct eleventh segment, is also discussed. — 3) The 
Amycteridae of the ‘Voyage de l‘Astrolabe’.’’ 1835. By E. W. Ferguson, 
M.B., Ch.M. — By the courtesy and kindness of the authorities of the Brus- 
sels Museum, and of Mr. A. M. Lea, of Tasmania, to whom the specimens 
were submitted, the author has had the opportunity of examining Bois- 
duval’s types of ten species, from Coll. Dejean, out of a total of nineteen 
described, the descriptions of the remaining nine being sufficiently full for 
satisfactory recognition. The synonymy of other species of the group is 
cleared up. — 4) Description of a new Lac-coccid (Genus Tachardia), from 
New South Wales. By W. W. Froggatt, F.L.S. — The coccid described 
has been found in two distant localities, Milton and Eden, but, in both 
places, so far, only upon quince trees. — Mr. Basset Hull exhibited an egg 
and nestlings of Oestrelata leucoptera Gould (White-winged Petrel), taken 
at Cabbage Tree Island, near the entrance to Port Stephens, N.S.W. — 
The egg was taken on the 4th December, 1910, on which date many birds 
were found sitting on fresh or slightly incubated eggs. The nests were placed 
amongst loose boulders or in crevices under rocks in a gully densely wooded 
with the Cabbage Palms (Livistona australis) to which the Island owes its 
name. Very little material was used to line the hollows in which the eggs 
were laid, merely a few shreds of fibre or dead fronds forming the nests. The 
eggs are pure white, without gloss, stout, rounded, oval in shape, average 
. dimensions 1,96 X 1,46 inches. The nestlings were taken on 30th January, 
1910: they were in down, bluish-grey on the upper surface, and greyish- 
white on the breast. The feet show the characteristic colouration of the adult 
bird, the basal half of the interdigital membrane being black. — Mr. A. R.
